Channeling of Protons through Carbon Nanotubes [PDF ebook] 

This book contains a thorough theoretical consideration of the process of proton channeling through carbon nanotubes. A brief summary of the theoretical and experimental results of studying ion channeling through nanotubes is first discussed. Then, the process of ion channeling is described briefly. After that, the crystal rainbow effect is introduced. A description how it was discovered, and present the theory of crystal rainbows, as the proper theory of ion channeling in crystals and nanotubes is provided. It is shown that the evolution of the angular distribution of channeled protons with the nanotube length can be divided in the cycles defined by the rainbow effect.
